Duro Dyne 14179 Pro Point Self Drilling Screws 3/4 Inch No. 8 Unslotted Hex Head Zinc Plated 100-pack

Product Description

The Duro Dyne 14179 Pro Point Self Drilling Screws are a reliable fastener solution built for HVAC sheet metal work, ductwork assembly, and light-gauge metal fabrication. Each screw measures 3/4 inches in length with a No. 8-18 TPI thread configuration, delivering clean, fast penetration into sheet metal without the need for a pilot hole. The self-drilling tip does the work of both a drill bit and a tapping tool in a single step, reducing labor time on the job and eliminating the need for pre-drilling. These screws are part of the Duro Dyne Pro Point collection, a line trusted by HVAC contractors and sheet metal workers for consistent performance across demanding installation environments. The unslotted hex head design allows for quick drive with a standard hex driver or nut driver, providing positive torque transfer and reducing cam-out during installation. A zinc plated steel construction offers corrosion resistance in typical indoor HVAC applications, making these screws well-suited for duct connections, equipment panels, access doors, and metal framing. Sold in a 100-pack, the 14179 is an economical choice for high-volume fastening tasks on commercial and residential HVAC projects. Whether you are assembling spiral duct, securing sheet metal collars, or fastening metal components in tight spaces, these screws provide the speed and reliability that trade professionals depend on. The 3/4 inch length is ideal for thin-gauge applications where a longer screw would risk over-penetration or interference with adjacent components.
